Subject: [PATCH 01/14] [CI] Run tests on AltLinux 10

Changes:
 - VIRTUALENV: virtualenv is explicitly executed through ${PYTHON}

The current problems

1) testgres/operations/helpers.py

    # Prepared pointer on function to get a name of system codepage
    _get_default_encoding_func = _make_get_default_encoding_func()

must be

    # Prepared pointer on function to get a name of system codepage
    _get_default_encoding_func = _make_get_default_encoding_func.__func__()

It is a problem of Python 3.9

2) These tests fail:

FAILED tests/test_simple.py::TestgresTests::test_logical_replication - psycopg2.errors.ProtocolViolation: could not create replication slot "mysub": ERROR:  could not access file "pgoutput": No such file or directory
FAILED tests/test_simple.py::TestgresTests::test_logical_catchup - psycopg2.errors.ProtocolViolation: could not create replication slot "mysub": ERROR:  could not access file "pgoutput": No such file or directory
FAILED tests/test_simple_remote.py::TestgresRemoteTests::test_logical_replication - psycopg2.errors.ProtocolViolation: could not create replication slot "mysub": ERROR:  could not access file "pgoutput": No such file or directory
FAILED tests/test_simple_remote.py::TestgresRemoteTests::test_logical_catchup - psycopg2.errors.ProtocolViolation: could not create replication slot "mysub": ERROR:  could not access file "pgoutput": No such file or directory

I suggest to fix these problems in the separated commits.

Subject: [PATCH 02/14] Initialization of Helpers._get_default_encoding_func is
 corrected [py3.9]

Python 3.9 does not undestand the following code:

_get_default_encoding_func = _make_get_default_encoding_func()

ERROR - TypeError: 'staticmethod' object is not callable

https://app.travis-ci.com/github/postgrespro/testgres/jobs/631402370

The code:
_get_default_encoding_func = _make_get_default_encoding_func.__func__()

is processed without problems.

Subject: [PATCH 03/14] run_test.sh is corrected

This patch fixes a problem with run the following commands:

"time <set env> converage run ..."

This command does not work (on altlinux-10 with custom build of PG).

I do not know why it happened and do not know why it was working early.

"<set env> time converage run ..." works without any problems.

We manually compile and "install" PG:
 - create a symlink /usr/local/bin/pg_config
 - create a symlink /usr/lib64/libpq.so.5

Manual bild fixes the following problem:
psycopg2.errors.ProtocolViolation: could not create replication slot "mysub": ERROR:  could not access file "pgoutput": No such file or directory

Failed tests:
 - TestTestgresCommon::test_logical_replication[remote_ops]

Subject: [PATCH 09/14] [CI] work with 'time' is corrected

AltLinux 10 does not support the sequential "time <set_env> coverage run ...".

Because this OS does not has a builtin command 'time' in bash.

https://forum.altlinux.org/index.php?topic=48342.0

We will install 'time' manually and use another command "<set_env> time coverage run ..." that works without problems but it requires to install 'time' on Ubuntu 2024.04, too.

AlpineLinux processes a new command line without any problems.
